METHOD OF MAKING SHADE HOLDERS.

SPECIFICATION forming part of Letters Patent No. 373,696, dated November Application filed February 23, 188-7. Srrial No. 229,145. (No model.)

To all whom it may concern:

Be it known that I, Janus graces, of Waterbury, in the county of New Haven and State of Connecticut, haveinvented a new Improvement in Methods of Making Shade-Holders; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-- Figure 1, a perspective view of a shadeholder complete; Fig. 2, a plan of the blank, showing the cuts by which the arms are formed as an integral part of the collar; Fig. 3, the collar and arms bent into shape preparatory to affixing the ring or completing the ends;

Fig. 4, the end of the arm as of book shape to embrace the shade.

This invention relates to an improvement in the manufacture of that class of holders for shades for gas and other burners which are composed of two or more arms extending from a center, the said arms terminating in suitable shape to grasp the edge of the shade, and the said center constructed for attachment to the burner. These holders have been varr ously constructed, the most common method being to attach several wire arms to a central collar, the arms bent into the required shape, and attached to a shade-ring, or terminating in hook shape, so as to support the shade; or, as in some cases, the collar-arms and shadering have been cut from a single piece of sheetmetal. In this case there is necessarily a very great loss of metal.

The object of my invention is to cheaply construct the arms as an integral part of the collar, whereby the attachment of the arms to the collar is avoided.

In carrying out my method I cut the arms and collar from a single piece of sheet metal,

the cuts to form the arms running from the cen-.

tral or collarportion ina voluteor scroll shape, as seen in Fig. 2,where I represent a blank to form three arms, A, B, and C, on a central collar, D. This requires three cuts, a, b, and 0,

Shape, as seen in Fig.

starting from points equidistant from thecenter and from each other, thesaid cuts running in a volute or scroll shape direction, and the cuts equidistant from each other, so that the material cut will be of substantially equal width from the starting-point outward. The length and width of the arms will be proportioned to the size or style of the holder to be produced. If the arms are to terminate in a shade-riug, Iprel'erably construct a tenou, (I, on the end of each arm, and this tenon may he formed in the process of cutting the blank, as seen in Fig. 2. After the cuts have thus been made, the several arms are drawn outward fro m the center and turned into vertical planes,

as seen in Fig. 3, and are given any desired curve or shape, which may be done by dies prepared for the purpose, not necessary to be herein described. perforation, E, by which it maybe attached to the burner. To the ends of the arms the shadowing F is secured, the shade-ring being constructed in the usual manner and so as to set upon the tenons of the arms,which are riv cted thereon, this method of attaching the shade being one common and well known, or, if preferred, the arms may terminate in hook 4, so as to embrace the edge of the shade. By this method of c0nstructicn the collar and arms are made in one integral piece and are cut from sheet metal with very tritling waste, it being understood that the cuts are made by dies prepared for the purpose, not necessary to be shown or described.

I claim- The method herein described of making shade-holders, consisting in cutting the arms and collar from a single disk, the cuts starting from the central collar and running there from in scroll shape, the cuts being substantially equidistant from each other, and then turn ing the arms from the central collar into the required shape, substantially as described.
